MDF 16-Way Contactor Board +2 Aux Sockets

MDF 16-Way Contactor Board — 16 × Mains + 2 × Aux Sockets

A professional MDF-housed contactor board for serious multi-light grow setups — safely switches 16 mains plugs plus 2 auxiliary sockets from a single timer input. Integrated timer drives two 40A contactors, plus two 24-hour always-on sockets for equipment that shouldn't cycle. The proper way to power a large grow room without plugging light ballasts into extension leads.

Why growers choose a 16-way contactor board:

• Switches 16 mains plugs from one timer — properly power a large multi-light setup
• Two 40A contactors handle serious load — up to 16 × 600W lights (~10kW total) with proper headroom
• Two 24-hour always-on sockets — for extraction fans, controllers, pumps that need constant power
• Integrated timer — configured and wired at the factory, just plug in and use
• MDF housing — dense acoustic/insulating material, not flimsy plastic
• Safe multi-light power management — properly switches inductive loads without damaging cheap relays
• Consolidates wiring — one wall feed, 16 organised outputs, tidier grow room

Who it's not for:

Overkill for small setups — for 1-4 lights, a simpler contactor or mechanical timer is cheaper. Check your mains circuit can handle the total load — 16 × 600W is 9,600W which typically needs a dedicated 40A feed. Installation of the mains connection should be done by a qualified electrician for safety and insurance.
